The lifting assembly is provided in the top portion of the gravity pier, and the lifting assembly is connected to the construction channel through the vertical drawing mechanism, so that the lifting assembly can adjust the height of the construction channel through the drawing mechanism to meet the needs of different
BL-5819
LU506346 construction heights. Compared to existing technologies, there is no need to erect the scaffold in a cumbersome manner, which improves the construction efficiency and the safety performance.
Specifically, as shown in Fig. 1, the construction platform for gravity pier comprises a lifting assembly, which is provided in the top portion of the gravity pier 1, the lifting assembly 1s mainly used to perform lifting action on the gravity pier 1. During specific use, the lifting assembly can be placed on the top portion of the gravity pier 1 by using a crane, compared to the complex erection of scaffold, the installation is very simple. The lifting assembly 1s provided with a vertical drawing mechanism 2, the drawing mechanism 2 is extended downwards to an outer side of the gravity pier 1, the drawing mechanism 2 is provided with a construction channel 3 surrounding the gravity pier 1 for construction personnel to perform construction, during the lifting process of lifting assembly, the lifting assembly can adjust the height of the construction channel 3 through the drawing mechanism 2 to meet the needs of different construction heights. That is, the operator needs to perform construction at different construction heights, and the requirements can be met by adjusting the height of the construction channel 3.
As shown in Figs. 1-3, in this example, the lifting assembly comprises the vertical support column 4 and the horizontal support frame 5. The extension direction of the vertical support column 4 is parallel to the height extension direction of the gravity pier 1, so that the vertical support column 4 is vertically arranged on the top surface of the gravity pier 1, which make it easy to install stably on the top surface of the gravity pier 1 during use. After use, it can be removed from the top surface of the gravity pier 1. In order to ensure the installation stability of the lifting assembly on the top portion of the gravity pier 1, there is provided with two vertical support columns 4, the top portion of two vertical support columns 4 are fixedly connected through the connecting plate 9, so that two vertical support columns 4 together to form a stable installation bracket, which helps to increase the stability of the lifting assembly. In addition, in order to further increase the installation stability of the vertical support column 4, the contact bottom plate can be installed at the bottom end of the vertical support column 4, and the cross-section area of the contact bottom plate is greater than that of the vertical support column 4, thereby increasing the contact area on the top surface of the vertical support column 4 and the gravity pier 1. The outer side of the vertical support column 4 is sleeved with a horizontal support frame 5, which can slide along the height extension direction of the vertical
BL-5819
LU506346 support column 4, the horizontal support frame 5 1s provided with a limit structure 6 which is used to limit the horizontal support frame 5 on the vertical support column 4; the drawing mechanism 2 is disposed on the horizontal support frame 5, which is used to slide with the horizontal support frame 5 on the vertical support column 4 to change the height of the construction channel 3.
In this way, when the adjusting of the construction height of the construction channel 3 1s needed, the horizontal support frame 5 is simply slid along the vertical support column 4 to the corresponding height, and then the limit structure 6 is used to limit the horizontal support frame 5 on the vertical support column 4.
For the convenience of driving the horizontal support frame 5 to slide along the vertical support column 4, the lifting assembly further comprises a lifting drive structure 7, which is disposed on the horizontal support frame 5. Specifically, the lifting drive structure 7 comprises a hydraulic cylinder, which is vertically fixed on a top surface of the horizontal support frame 5, and a hydraulic push rod of the hydraulic cylinder is passed through the horizontal support frame 5 and is abutted against the top surface of gravity pier 1. The hydraulic cylinder is connected to an external hydraulic system.
In this example, there are two hydraulic cylinders respectively located at the both ends of the horizontal support frame 5, which facilitate balanced driving of horizontal support frame 5 for lifting.
As shown in Figs. 1, 3-4, the limit structure 6 comprises a fixed bracket 601, which is fixedly connected to the horizontal support frame 5, and the fixed bracket 601 is slidably provided with a telescopic rod 602, the vertical support column 4 is uniformly provided with multiple limit holes 401 along the height direction, and the shape of the limit hole 401 is adapted to the telescopic rod 602, so that when the horizontal support frame 5 lifts or falls to a certain height, the positioning of the horizontal support frame 5 is completed by extending the telescopic rod 602 into the limit hole 401. In order to push the telescopic rod 602 to expand and retract smoothly, the hydraulic cylinder is fixedly connected to the fixed bracket 601 as the reciprocating drive source 11, the push rod of the hydraulic cylinder is fixedly connected to telescopic rod 602. Wherein, in order to ensure smooth sliding between the telescopic rod 602 and the fixed bracket 601, the fixed bracket 601 is provided with a sliding groove 6011, and the telescopic rod 602 is slid on the sliding groove 6011.
For the gravity pier 1 with constant width dimension, the above technical solution can already meet the construction requirements. However, the gravity pier 1 also has the situations where the
BL-5819
LU506346 width dimension changes in the height direction. At this time, if only the height of the construction channel 3 is adjusted, the horizontal distance between the construction channel 3 and the gravity pier 1 will also change as the width of the gravity pier 1 changes. If the width dimension of the construction channel 3 is not adjusted accordingly, it will make it inconvenient for operators 5 standing on the construction channel 3 to perform construction. In order to solve this technical problem, as shown in Fig. 5, the construction channel 3 comprises two linear components 301 and two arc-shaped components 302, two linear components 301 are provided in both sides of the gravity pier 1 and are connected to the drawing mechanism 2, and two arc-shaped components 302 are respectively provided in both ends of the linear components 301 and are detachably connected to the linear components 301; the arc-shaped components 302 have multiple specifications, and the radians of the arc-shaped component 302 with different specifications are different, which is used to suitable for two linear components 301 with different distances. That is, in order to adapt to the different width dimensions of the gravity pier 1 corresponding to different heights, the distance between two linear components 301 can be adjusted, and the dimension of the construction channel 3 can be adjusted accordingly by replacing the arc-shaped component 302 with different specifications. The construction channel 3 1s more adaptable to the width of the gravity pier 1 at different heights, which is easier for construction worker to perform construction operation. At the same time, the construction platform for gravity pier further comprises a width adjustment assembly, which is used to adjust the horizontal distance between two linear components 301 of the — construction channel 3.
As shown in Figs. 3 and 6, the width adjustment assembly comprises four screws 8, which are evenly provided in both sides of the horizontal support frame 5 and are rotationally mounted on the horizontal support frame 5, and one side of each screw 8 away from the gravity pier 1 is threaded to one drawing mechanism 2 for driving the drawing mechanism 2 away from or close to the gravity pier 1, one side of the screw 8 closed to the gravity pier 1 is connected to the motor as a rotating drive source 10 to drive screw 8 to rotate.
The drawing mechanism 2 comprises a thread guide block 201, a drawing rod 202 and a supporting component 203, the thread guide block 201 is provided in the top portion of the drawing rod 202 and is threaded to the screw 8, and the thread guide block 201 is slidably matched with the
BL-5819
LU506346 horizontal support frame 5. At the same time, the outside of the thread guide block 201 is a rectangular structure, the rectangular sliding hole is provided inside the corresponding horizontal support frame 5. The inside of the thread guide block 201 is threaded to the screw 8 by the thread, and the outside of the thread guide block 201 is in sliding fit with the rectangular sliding hole. When screw 8 rotates, it will drive the thread guide block 201 to slide inside the sliding hole; the supporting component 203 is provided in the bottom portion of the drawing rod 202 and perpendicular to the drawing rod 202, which is provided in the bottom portion of construction channel 3 for supporting the construction channel 3. Wherein, the length of supporting component 203 is close to the width of construction channel 3, thus supporting construction channel 3 more stably. In order to further ensure the connection stability of construction channel, the construction channel 3 is fixedly connected to the drawing rod 202 by using a screw.
As shown in Figs. 1, 3 and 7, in order to ensure the sliding stability between the horizontal support frame 5 and the vertical support column 4, the shaking is reduced during the sliding process of the horizontal support frame 5, thereby ensuring the safety of the construction channel 3. The side surface of the vertical support column 4 is provided with a guide groove 402, and the position opposite to the guide groove 402 on the horizontal support frame 5 is provided with a guide convex block 501 which is adapted to the guide groove 402. The horizontal support frame 5 can be a single component or a combination of multiple components.
Specifically, during use, when the construction channel 3 is needed to rise, firstly, the telescopic rod 602 is retracted from the limit hole 401, then the lifting drive structure 7 is activated to drive the horizontal support frame 5 to rise. When the rise reaches the required height, the telescopic rod 602 is extended and is inserted into the corresponding the limit hole 401. The principle of the downward adjustment and upward adjustment of the construction channel 3 is the same and will not be repeated.
When adjusting the width of the construction channel 3 is needed, firstly, the arc-shaped components 2302 at both ends are removed, and then the rotating drive source 10 is started synchronously, the screw 8 is drove by the rotating drive source 10 to rotate, thereby the distance between the two linear components 301 is adjusted, then, the corresponding specifications of the arc-shaped component 302 and the linear component 301 is selected for installation.
